Definitions

  • the technical field relates to a wrapping apparatus for wrapping a load with a packaging material, and more particularly, to a wrapping apparatus having a film delivery assembly. It also relates to a method for wrapping a load and delivering a film for wrapping a load.
  • Wrapping apparatuses have been developed to stretch, dispense, and wrap stretch packaging material around a load.
  • the four vertical sides of the load are typically covers with a stretchable packaging material (or film) such as polyethylene packaging material.
  • Stretch wrapping can be accomplished by a turntable, a rotating arm, a vertical rotating ring, or a horizontal rotating ring wherein relative rotation is provided between the load and a packaging material dispenser to wrap packaging material about the sides of the load.
  • Loads are continuously packaged in the wrapping apparatus until the packaging material supply mounted to the packaging material dispenser is emptied. Then, the packaging material dispenser must be reloaded with a new packaging material supply. Alternatively, even if the packaging material dispenser is not emptied, there may be a need to change the packaging material, for instance, to wrap a load with a packaging material having different properties. For reloading the packaging material dispenser with a new packaging material supply or changing the packaging material, an operator must enter the wrap zone and, consequently, energy has to be removed from the apparatus. Furthermore, when the wrapping apparatus is restarted, energy has to be restored beforehand. There is thus a downtime period associated with either reloading the packaging material dispenser or changing the packaging material.
  • a packaging material dispenser for a wrapping apparatus comprising: a frame having at least a first packaging material supply and a second packaging material supply, the frame being selectively configurable into at least a first configuration wherein the first packaging material supply is positioned in a packaging material dispensing configuration and a second configuration wherein the second packaging material supply is positioned in the packaging material dispensing configuration.

  • each of the at least first packaging material supply and second packaging material supply comprises a roll support for supporting a roll of packaging material to be dispensed.
  • At least one of the at least first packaging material supply and second packaging material supply is slidably mounted to the frame so as to be vertically displaced along the frame.
  • the at least first packaging material supply and second packaging material supply is displaced from the packaging material dispensing configuration upon the at least first packaging material supply and second packaging material supply being depleted of packaging material or a different type of packaging material being required.
  • the load press further comprises a frame extending above the upper surface of the load and at least one main actuator mounted to the frame and operatively connected to at least one of the central press section and the peripheral press section for configuring the at least one of the central press section and the peripheral press section in the operative and disengaged configurations.
  • the at least one main actuator can operatively be connected to the central press section and can be actuable for selectively configuring the central press section in the operative and disengaged configurations.
  • the load press further comprises a peripheral press actuator connecting the central press section and the peripheral press section together and actuable for selectively configuring the peripheral press section in the operative and disengaged configurations when the central press section is configured in the operative configuration.
  • the peripheral press actuator can actuate the peripheral press section in the disengaged configuration, thereby spacing the peripheral press section apart from the upper surface of the load, and can further actuate the central press section in the operative configuration while the upper surface of the load is at least partially wrapped.
  • a packaging method for wrapping a load comprising: clamping a section of a packaging material supplied by a packaging material supply mounted to a packaging material dispenser in a packaging material dispensing configuration; moving the clamped section of the packaging material from the packaging material dispenser towards the load; and wrapping the load with the packaging material.
  • wrapping the load comprises rotating the load about itself.
  • a packaging wrapping apparatus comprising: a load support frame; a packaging material dispenser having at least one packaging material supply configurable in a packaging material dispensing configuration; and a packaging material seeking assembly having a packaging material clamp displaceable between the packaging material dispenser and the load support frame for sizing a packaging material supplied by one of the at least one packaging material supply configured in a packaging material dispensing configuration.

  • the load support frame comprises a turntable and at least one conveyor for transporting a load toward and away from the turntable.
  • the packaging material clamp is displaced towards the turntable and rotated therewith.
  • the wrapping apparatus further comprises an enclosure enclosing an area containing at least in part the load support frame, the packaging material seeking assembly, and the packaging material dispenser, the enclosure comprising a plurality of openings for permitting access to the area.
  • the enclosure can comprise a plurality of mechanical barriers and a plurality of light curtains defining the openings permitting access to the area.
  • at least two of the light curtains are oppositely disposed across one of the openings, the two light curtains cooperating so as to create a light curtain barrier across said opening and configured for operating between an active configuration wherein crossing of the light curtain barrier result in shutdown of operation of the wrapping apparatus, and an inactive configuration wherein crossing of the light curtain barrier results in continued operation of the wrapping apparatus.
  • a method for wrapping an upper surface of a load comprising: configuring a central press section and a peripheral press section in an operative configuration wherein the central press section and the peripheral press section abut the upper surface of the load; wrapping a first section of the load; configuring the peripheral press section in a disengaged configuration wherein the peripheral press section is spaced-apart from at least a part of the upper surface of the load; and wrapping a second section of the load, the second section including at least a part of the upper surface of the load.

  • the apparatus 20 further includes a packaging material dispenser 28 , spaced-apart from the turntable 24 , for dispensing the packaging material for wrapping the loads on the turntable 24 .
  • the turntable 24 and both conveyors 26 define together a longitudinal axis of the apparatus 20 .
  • the packaging material dispenser 28 is aligned with the turntable 24 ; but defines therewith a transversal axis, substantially perpendicular to the longitudinal axis. In other words, the packaging material dispenser 28 is not aligned with the conveyors 26 .

  • the packaging material dispenser 28 includes a vertically elongated frame 38 .
  • the frame 38 is rotatably mounted and can rotate around a hub (not shown).
  • the packaging material dispenser 28 is a turret system, i.e. a rotating device, holding a plurality of packaging material rolls 25 , as it will be described in more detail below.
  • the packaging material dispenser 28 For supporting the packaging material rolls 25 , the packaging material dispenser 28 further includes a plurality of packaging material supplies 42 (referred to herein as “roll carriages” 42 ) slidably mounted on the frame 38 .
  • the roll carriages 42 provide a supply of the packaging material.
  • the packaging material dispenser 28 includes four roll carriages 42 , the roll carriages 42 being slidably mounted to the frame 38 in opposed pairs. Each one of the roll carriages 42 can be displaced vertically between a raised position and a lowered position. The vertical movement of each one of the roll carriages 42 can be independent from the other roll carriages 42 .
  • roll carriages 42 can be replaced by stationary supplies of the packaging material, i.e. ones that are not vertically translatable.
  • the turret system of the packaging material dispenser 28 allows multiple roll carriages 42 to be pre-loaded with rolls 25 of packaging material. It further allows specific rolls of packaging material to be brought to a packaging material dispensing configuration.
  • the packaging material dispensing configuration refers to the displacement, typically by rotation, and arrival of the packaging material dispenser 28 at a position adjacent to and facing the turntable 24 . In such a configuration, the packaging material dispenser 28 is ready to dispense the packaging material.
  • the other packaging material dispenser(s) are then configured in an inoperative configuration.

  • the roll support 44 is constructed to rotatably support a roll 25 of packaging material as it unwinds.
  • the roll carriages 42 further include a pre-stretch assembly 46 . As the roll 25 of packaging material unwinds, the packaging material moves from the roll 25 to the pre-stretch assembly 46 .
  • the packaging material is supplied from one of the roll carriages 42 to the load for wrapping same. More particularly, the packaging material is supplied from the roll carriage 42 which is in the packaging material dispensing configuration described above. As the turntable 24 rotates, the packaging material is wrapped around the load.
  • the packaging material is supplied by the roll carriage 42 currently in the packaging material dispensing configuration, which corresponds to the roll carriage 42 which is adjacent to the turntable 24 and opposed to the opening 36 b . Since the roll carriages 42 are mounted to a rotatable frame 38 , the packaging material can be supplied from anyone of the roll carriages 42 .
  • the frame 38 is rotated until the desired roll carriage 42 is in the packaging material dispensing configuration, i.e. adjacent to the turntable 24 .
  • packaging material dispenser 28 can be rotated by different mechanisms.
  • the configuration, size, and shape of the packaging material dispenser 28 including its roll carriages 42 can differ from the embodiment shown.
  • the roll carriage 42 can be reloaded with a new roll 25 of packaging material without interrupting the operation of the apparatus 20 or the wrapping cycle for a relatively long period of time. More particularly, when a roll 25 of packaging material (e.g. film) on one of the roll carriages 42 is empty, the emptied roll carriage 42 can be displaced so as to be positioned adjacent to the opening 36 b . This displacement, typically by rotation, and positioning of the empty roll carriage 42 adjacent to the opening 36 b places the empty roll carriage 42 in a reloading configuration. Once in the reloading configuration, the empty roll carriage 42 is ready to be reloaded by an operator with one or more rolls 25 of packaging material.
  • packaging material e.g. film
  • each roll carriage 42 can support a different type of packaging material (thickness, size, color, specification) and the apparatus 20 or its operator can index the apparatus 20 so as to select the desired film. If the machine automatically indexes the suitable packaging material, the selection is based on a programmed recipe.
  • the barriers 32 and light curtains 34 or zone scanners provided near the opening 36 b which can be accessed by the operators for reloading the rolls 25 of packaging material. More particularly, the opening 36 b permits access to the roll carriage 42 when it is positioned in the packaging material reloading configuration described above.
  • Items 34 a and 34 b are both light curtain barriers, light beams, or zone scanners.
  • the light curtains 34 a are active while the light curtains 34 b are inactive.
  • active refers to the tendency of a given light curtain to shut down the apparatus 20 if the barrier it creates is crossed.
  • the light curtains 34 a are made inactive, and the light curtain 34 b is activated, thereby protecting the area surrounding the packaging material dispenser 28 and preventing the operator from crossing into opening 36 b .
  • the light curtains 34 a are again activated and the light curtain 34 b is made inactive, allowing the operator to interact with the roll carriage 42 adjacent to the opening 36 b .
  • the light curtains 34 a or zone scanners can be installed under the turret to monitor the secure areas.
  • Each one of the roll carriages 42 includes a starting clamp assembly 52 having two spaced-apart grips.
  • the operator positions a tail of the packaging material into the starting clamp assembly 52 .
  • the clamp assembly 50 includes a packaging material clamp 56 operatively connected to a displacement mechanism 58 for displacing the packaging material clamp 56 from the turntable 24 to the packaging material dispenser 28 , and vice-versa.
  • the displacement mechanism 58 includes a translatable arm. More particularly, the displacement mechanism 58 displaces the packaging material clamp 56 in a packaging material seeking configuration.
  • the packaging material seeking configuration refers to the displacement of the packaging material clamp 56 from the turntable 24 to a position near to a roll carriage 42 , which is itself in the dispensing configuration described above.
  • the displacement mechanism 58 extends the packaging material clamp 56 from a position near the turntable 24 , to a position away from the turntable 24 and toward the packaging material dispenser 28 . This places the packaging material clamp 56 in a position to receive packing material from the roll carriage 42 .
  • the packaging material clamp 56 comprises two displaceable legs 56 a , 56 b which are operable between an open configuration where the legs 56 a , 56 b move away from one another so as to receive the packaging material therein, and a closed configuration where the legs 56 a , 56 b are displaced towards each other so as to clamp the packaging material placed between them.
  • the packaging material clamp 56 is displaced and positioned near the packaging material dispenser 28 as per the packaging material seeking configuration described above.
  • the legs 56 a , 56 b of the packaging material clamp 56 are in the opened configuration, and the tail of the packaging material is held by the starting clamp assembly 52 .
  • the two spaced-apart clamps of the starting clamp assembly 52 are opened to release the packaging material into the opened legs 56 a , 56 b of the packaging material clamp 56 , which are then transitioned to the closed configuration so as to grip and secure the tail of the packaging material within the packaging material clamp 56 .
  • the clamp assembly 50 is then displaced towards the turntable 24 and away from the packaging material dispenser 28 , via the displacement mechanism 58 , for example.
  • the clamp assembly 50 thus enters into a wrapping configuration for wrapping the load, as will now be described.
  • the wrapping configuration relates to the wrapping of the load.
  • the clamp assembly 50 which now contains a tail of the packaging material, is withdrawn towards the turntable 24 .
  • the packaging material thus spans between the turntable 24 (more specifically, the clamp assembly 50 ) and the packaging material dispenser 28 (more specifically, the packaging material roll 25 ). Therefore, the packaging material can be spun off the packaging material roll 25 as more packaging material is needed.
  • the turntable 24 is then rotated. Since the clamp assembly 50 has been withdrawn toward the turntable 24 and forms a part thereof, the clamp assembly 50 rotates along with the turntable 24 . This rotation of the clamp assembly 50 causes the packaging material to be wrapped around the load, and further causes additional packaging material to be unfurled from the packaging material roll 25 .
  • the clamp assembly 50 can release the tail of the packaging material it held because the load has now been sufficiently wrapped with packaging material. After the rotations have ceased, the clamp assembly 50 can again be used to sever the connection of packaging material which now unites both the wrapped load and the packaging material roll 25 .
  • the clamp assembly 50 achieves this by cutting the packaging material and gripping a new tail of packaging material it has just cut. Therefore, the clamp assembly 50 , which is still gripping the new tail of packaging material, is ready to be rotated in the next wrapping cycle.
  • the packaging material dispenser 28 is rotated until a selected one of the roll carriages 42 is configured in the dispensing configuration, i.e. it is adjacent to the turntable 24 . Then, the same steps are carried out, as detailed above, for sizing the packaging material held by the starting clamp assembly 52 of the selected roll carriage 42 , and displacing it towards the turntable 24 .
  • the packaging material dispenser 28 When a packaging material roll 25 is emptied, the packaging material dispenser 28 is rotated until the selected roll carriage 42 is configured in the dispensing configuration discussed above. Then, the packaging material clamp 56 is displaced towards the packaging material dispenser 28 and the same steps are carried out, as detailed above, for sizing the packaging material, held by the starting clamp assembly 52 of the selected roll carriage 42 , and displacing it towards the turntable 24 .
  • the apparatus 20 enables the packaging material (e.g. a film) to be brought from the roll support 44 of the roll carriage 42 to the turntable 24 , or vice-versa, without operator intervention.
  • This enables the packaging material dispenser 28 (i.e. turret system) to index to the next roll carriage 42 and reload the packaging material into the clamp assembly 50 automatically without the involvement of an operator.
  • the wrapping apparatus 20 is also provided with a top press 60 and, more particularly, a dual stage top press 60 positioned above the turntable 24 for securing a load thereon by applying pressure.
  • the top press 60 has a central (or inner) press 62 and a peripheral (or outer) press 64 which can operate independently of one another, if required.
  • the top press 60 provides stability by countering the centrifugal forces generated when the load is being wrapped through rotation. These centrifugal forces may result in the load being spun out, or ejected from, the wrap zone 48 or the turntable 24 .
  • the peripheral press 64 can surround the central press 62 .
  • the central press 62 and the peripheral press 64 are actuatable independently of each other, as it will be described in more detail below.
  • the dual stage top press 60 is mounted to a frame 66 which extends vertically above the turntable 24 and the load being wrapped.
  • the frame 66 includes a main actuator 68 mounted to the frame 66 and connected to the central press 62 .
  • the main actuator 68 applies a force which displaces the central press 62 between an operative configuration wherein the central press 62 applies pressure on the upper surface of the load located on the turntable 24 , and a disengaged configuration wherein the dual stage top press 60 is spaced-apart from the load.
  • the central press 62 when wrapping a load, the central press 62 is configured in the operative configuration and maintains a substantially constant hold in the center of the load.
  • the peripheral press 64 is selectively configurable in the operative and disengaged configurations. When wrapping the lateral walls of the load, the peripheral press 64 is configured in the operative configuration and applies a hold on the peripheral portion of the upper surface of the load. When wrapping the upper portion of the lateral walls and the peripheral portion of the upper surface of the load, the peripheral press 64 is configured in the disengaged configuration, and is spaced-apart from the upper surface of the load.
  • the optionally pneumatic actuator 72 connecting the central and peripheral presses 62 , 64 allows for maintaining a substantially constant hold in the center of the load and while still permitting the peripheral press 64 to be lifted off the top periphery of the load so as to allow for film overwrap. This allows for wrapping at least a portion of the top of the load while maintaining load stabilization.
  • the top press 60 can have more than two sections, i.e. more than the central and the peripheral press sections 62 , 64 .
  • the shape and the configuration of the press sections 62 , 64 can differ from the embodiment shown in the attached drawings.
  • each press section 62 , 64 can have its own actuator and the actuators of the press sections 62 , 64 can be independently actuable.
  • the embodiments of the wrapping apparatus 20 and corresponding parts thereof consist of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential to the invention and thus should not be taken in their restrictive sense. It is to be understood, as also apparent to a person skilled in the art, that other suitable components and cooperation therein between, as well as other suitable geometrical configurations, may be used for the wrapping apparatus according to the present invention, as it will be briefly explained herein and as can be easily inferred here from by a person skilled in the art. Moreover, it will be appreciated that positional descriptions such as “above”, “below”, “left”, “right” and the like should, unless otherwise indicated, be taken in the context of the figures and should not be considered limiting.
